Trying to do the equivalent to this shell fragment set -A MyArray1 q w e r t y set -A MyArray2 a s d f g h x=1 eval print \${MyArray${x}} If you're familiar with unix, the first parse (eval) expands ${x} to 1, and removes the The second parse expands to ${MyArray1} and prints q w e r t y...

ps -fe | grep [o]ra_ avoids the 2nd pipe and associated process

BTW, how are you eliminating your grep process from the output ?

6 seconds to print 1st line seems a long time. Once it starts printing, does it stall? Does aix have vmstat, or top? (or something else) Start vmstat or top before you run ps. Observe behaviour when ps starts. Look for excessive paging, context switches, run queue How long does it take for...

How long does ps -fe take (ie. without the grep)

can you cat the file and see normal text? There are special characters in the file, but your command history is in plain text. (well, it is on every flavour of *nix I've worked on) Maybe the string you're grepping for doesn't exist. Aged out, maybe? What's your HISTSIZE set to ? I'm assuming...

From the ksh man page... Invocation If the shell is invoked by exec(2), and the first character of argument zero ($0) is -, then the shell is assumed to be a login shell and commands are read from /etc/profile and then from either .profile in the current...

sdiff -s file1 file2 Any good?

yep that would work, but an OS upgrade might re-install the original script. Personally, I would leave the rc3 as is, and get the S?? startup script call the korn shell script. BTW, the S?? should be a sym link to the script in /etc/init.d (but you probably already knew that).

vi /etc/default/telnetd Insert BANNER=""

revert to root's original .profile add the following line:- ENV=~/.kshrc in .profile create .kshrc in root's home directory put all the ksh specific commands in .kshrc login as root ksh
